Balbaroo is an extinct genus of quadrupedal kangaroo that once lived in Australia. [2]
The genus was erected in 1983 to describe a new species of early marsupials, Balbaroo camfieldensis. [1] Since then, it has been determined that members of the genus possessed sharp canines. Despite the sharp canines, the presence of low-crowned bilophodont molars seems to indicate an herbivorous diet. [2]
Four species are currently recognised:
Tree-kangaroos are marsupials of the genus Dendrolagus, adapted for arboreal locomotion. They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, along with some of the islands in the region. All tree-kangaroos are considered threatened due to hunting and habitat destruction. They are the only true arboreal macropods.
The order Peramelemorphia includes the bandicoots and bilbies. All members of the order are endemic to Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail. Their size varies from about 140 grams up to 4 kilograms, but most species are about one kilogram.
Thylacoleo is an extinct genus of carnivorous marsupials that lived in Australia from the late Pliocene to the Late Pleistocene, often known as marsupial lions. They were the largest and last members of the family Thylacoleonidae, occupying the position of apex predator within Australian ecosystems. The largest and last species, Thylacoleo carnifex approached the weight of a lioness. The estimated average weight for the species ranges from 101 to 130 kg.
The dingiso, also known as the bondegezou or bakaga, is an endangered, long-tailed marsupial found only in mountain forests on the west of the island of New Guinea. It is a species of tree-kangaroo, which are mammals native to Australia and New Guinea that feed on leaves or other plant matter. It belongs to the macropodid family (Macropodidae) with kangaroos, and carries its young in a pouch like most other marsupials. Though sacred to the local Moni people, it is still threatened by hunting and habitat loss.
The Hypsiprymnodontidae are a family of macropods, one of two families containing animals commonly referred to as rat-kangaroos. The single known extant genus and species in this family, the musky rat-kangaroo, Hypsiprymnodon moschatus, occurs in northern Australia. During the Pleistocene, this family included the megafauna genus Propleopus.
Hypsiprymnodon is a genus of macropods. The sole extant species is Hypsiprymnodon moschatus, the musky rat-kangaroo. The genus includes four known fossil species.
Palorchestes is an extinct genus of large terrestrial, herbivorous Australian marsupial of the family Palorchestidae, living from the Miocene through to the Late Pleistocene. Like other palorchestids, it had highly retracted nasal region suggesting that it had a prehensile lip, as well as highly unusual clawed forelimbs that were used to grasp vegetation.
Ekaltadeta is an extinct genus of marsupials related to the modern musky rat-kangaroos. Ekaltadeta was present in what is today the Riversleigh formations in Northern Queensland from the Late Oligocene to the Miocene, and the genus includes three species. The genus is hypothesized to have been either exclusively carnivorous, or omnivorous with a fondness for meat, based on the chewing teeth found in fossils. This conclusion is based mainly on the size and shape of a large buzz-saw-shaped cheek-tooth, the adult third premolar, which is common to all Ekaltadeta.
The Macropodiformes, also known as macropods, are one of the three suborders of the large marsupial order Diprotodontia. They may in fact be nested within one of the suborders, Phalangeriformes. Kangaroos, wallabies and allies, bettongs, potoroos and rat kangaroos are all members of this suborder.
Bettongs, species of the genus Bettongia, are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat.
Protemnodon is an extinct genus of megafaunal macropodids that existed in Australia, Tasmania, and New Guinea in the Pliocene and Pleistocene. Members of this genus are also called giant kangaroos.
Hulitherium tomasetti is an extinct zygomaturine marsupial that lived in New Guinea during the Pleistocene. The species name honours Berard Tomasetti, a Catholic priest in Papua New Guinea, who brought the fossils to the attention of experts.
Nambaroo is an extinct genus of macropod marsupial from the late Oligocene to the early Miocene of Australia.
Propleopus is an extinct genus of marsupials. Three species are known: P. chillagoensis from the Plio-Pleistocene, and P. oscillans and P. wellingtonensis from the Pleistocene. In contrast to most other kangaroos, and similar to their small extant relative, the musky rat-kangaroo, they were probably omnivorous.
Ganguroo is a genus of fossil macropods found at Riversleigh in Australia, material dating from the Middle to Late Miocene Epoch. The type species of the genus is Ganguroo bilamina, published in 1997. Two recently described species, Ganguroo bites and Ganguroo robustiter, have also been placed in this genus.
The Macropodidae are an extant family of marsupial with the distinction of the ability to move bipedally on the hind legs, sometimes by jumping, as well as quadrupedally. They are herbivores, but some fossil genera like Ekaltadeta are hypothesised to have been carnivores. The taxonomic affiliations within the family and with other groups of marsupials is still in flux.
Notamacropus is a genus of small marsupials in the family Macropodidae, commonly known as wallabies. The term is derived from the Latin nota "stripe" and macropus "kangaroo", referencing the distinct facial stripe of many extant genus members and their phylogenetic relationship to other kangaroos.
Hypsiprymnodon karenblackae is a fossil species describing a small marsupial extant in Australia during the Early to Middle Miocene Epoch. The material was collected at the Australian Fossil Mammal Sites (Riversleigh). The taxon was published in 2014, along with several other new species of the genus Hypsiprymnodon, known as musky rat-kangaroos. The morphology of the teeth suggest it existed in a wet rainforest environment, similar to the ecological conditions of the extant species, the musky rat-kangaroo. The type specimen was collected at the Camel Sputum site, classified as a Faunal Zone B (Miocene) deposit at Riversleigh in northwestern Queensland, The epithet is for Dr. Karen Black's contribution to palaeontology in Australia, especially the Riversleigh fossils.
Karen H. Black, born about 1970, is a palaeontologist at the University of New South Wales. Black is the leading author on research describing new families, genera and species of fossil mammals. She is interested in understanding faunal change and community structure in order to gain new understandings of past, current and future changes in biodiversity which are driven by climate.
Bohra is an extinct genus of macropod from the Plio-Pleistocene of Australia. It is closely related to modern tree kangaroos (Dendrolagus), and like them is thought to have had an arboreal lifestyle, with some species of Bohra substantially exceeding living tree kangaroos in size.
